3. CONSTANT SPRING HANGERVertical-Mount TypeTable 3-2-3Model Type Outline Application Maximum CapacityCSBC1Hanger is vertically mounted on structural steeland applicable where installation space islimited between structural steel and piping orequipment to be supported.174.2 ～ 9,218kN・mmD1 Pipe or equipment is to be supported frombelow.3.3 Construction and FeaturesThe typical construction of the Constant Spring Hangers is illustrated in Fig. 3-1, which specificallyshows a Type B1A of Model CSH.Design is mostly common to all models, although top connections and spring housing direction varywith the respective types. For providing large load capacities,exceeding our standard design, Large sizesof constant hangers can be equipped with dual springs under special design. Major design features arebased on the following specifications:1. These Constant Spring Hangers using coil spring are designed and fabricated for maximumperformance on the basis of SANWA TEKKI'S many years of experience in the field.2. The housing is of such sturdy construction that any contact with adjacent equipment duringtransportation or operation will not cause damage or deterioration of function. A slit is provided atthe lower portion of spring housing for visual checking of coil spring.3. Friction at all rotating points is minimized by using dry bearings which withstand enormous loadsand do not require lubrication.4. The load holder permits a rod movement of at least 4°from vertical, so that horizontal movementsof piping or equipments can be followed.5. Unless otherwise specified, STC' s Constant Spring Hanger is pre-set before shipment at Top of thetravel scale in case the thermal displacement direction is downward from Cold condition to Hotcondition, and is pre-set at Bottom of the travel scale in case the thermal displacement direction isupward.If specified, the Constant Spring Hanger can be pre-set to any position on its travel scale.17
